Antenna data

Stationary Antennas were down for 3.59% of the total time across all Stationary Antennas. Inidividual Antennas were down for a total of 572.83 days out of a total of 15969.34 days of total time across all Stationary Antennas. Biomark Antennas were down for 2.06% of the total time across all Biomark Antennas. Inidividual Antennas were down for a total of 31.35 days out of a total of 1525.72 days of total time across all Biomark Antennas.

Stationary Antennas detected 1309 fish that were not detected by mobile, biomark, or recapture methods. Biomark Antennas detected 148 fish that were not detected by mobile, stationary, or recapture methods. Mobile Antennas detected 1041 fish that were not detected by biomark, stationary, or recapture methods. There were 198 fish recaptured that were not detected by biomark, stationary, or recapture methods.

Before and After

Before the Connectivity Channel was built, there were 29 upstream journeys from Hitching Post Antenna or Windy Gap Biomark Antenna below the dam to Confluence Antenna by non-Avian Predated fish and 36 downstream journeys from Confluence Antenna to Hitching Post Antenna or Windy Gap Biomark Antenna below the dam, over the course of 1167.14 days. This equates to one upstream journey every 40.25 days and one downstream journey every 20.78 days. Since the Connectivity Channel was built, there have been 77 upstream journeys from Hitching Post Antenna or Windy Gap Biomark Antenna to Confluence Antenna by non-Avian Predated fish AFTER Channel was built and 85 downstream journeys from Confluence Antenna to Hitching Post Antenna or Windy Gap Biomark Antenna below the dam, over the course of 748 days. This equates to one upstream journey every 9.71 days and one downstream journey every 8.8 days on average.

In comparison, before the Connectivity Channel was built, there were 275 upstream journeys from Red Barn Antenna to Hitching Post Antenna by non-Avian predated fish and 362 downstream journeys from Hitching Post Antenna to Red Barn over the course of 1167.14 days. This equates to one upstream journey every 4.24 days and one downstream journey every 3.22 days. Since the Connectivity Channel was built, there have been 159 upstream journeys from Red Barn Antenna to Hitching Post Antenna by non-Avian predated fish and 246 downstream journeys from Hitching Post Antenna to Red Barn over the course of 748 days. This equates to one upstream journey every 4.7 days and one downstream journey every 4.74 days on average.

Avian Predation

Throughout the duration of the study, we have identified 59 fish that have been predated by birds. These tags are found a few different ways: * By identifying missing antennas in their encounter history, ie hitting an antenna different than the ones we’d expect them to hit * Identifying instances where a tag moved quickly, or disproportionately far throughout its encounter history or even just one move
